[JAVA] instanseof : Object 의 타입알기

If you just want to know if an object is an instance of or extends a certain class, or implements a certain interface, you can use the instanceof keyword. 

public void myMethod(Object obj) {
    if (obj instanceof String) {
        System.out.println("It's a String");
    }
    else {
        System.out.println("It's not a String");
    }
}
